Joined the Cambodia Intro trip solo and can;t fault anything about the experience. The group leader (Izabela!!) was incredibly friendly, welcoming and communicative throughout the whole trip and prior.
The country is extremely relaxed and the people are super welcoming, it hard to go anywhere without being greeted or waved at by the local children. Every experience was well organised and the guide - whether that be a local or the tour leader - was knowledgeable and open to questions. I couldn;t recommend Intro enough to anyone wanting to travel solo or with friends! °
